Just thought this might be of use / interest ? have been in contact with a particular Ebay seller about having an "extension" strap piece made for one of my bags .. they have been amazingly helpful (it's not one of their "standard" items, it's a "custom" job) so I felt it'd be nice to pass their info' on as I know we (all) sometimes want extra / additional / replacement straps.
